Patented June 23, 1931 i UNITED STATES DEQFC-i Hedi PATENT OFFICE HERMAN E. ALTGEL'I, OF SOUTH BEND, INDLANA, ASSIGNOR, BY MESNE ASSIGNMENTS, TO OLIVER FARM EQUIPMENT COMPANY, A CORPORATION OF DELAWARE TRACTOR Application filed March 19, 1928. Serial No. 262,930.

This invention relates to improvements in tractors and more particularly to means to facilitate connection therewith of agricultural appliances,one object of the invention being to provide a tractor with simple and eflicient anchoring or" supporting and connecting means for agricultural implements and operating and controlling means therefor, and to so locate and secure such means to the tractor that the same may be easily fixed to the tractor and project in opposite directions laterally therefrom in a manner to support and constitute attaching means for implements of various kinds.

With this and other objects in view, the invention consists in certain novel features of construction and combinations of parts as hereinafter set forth and pointed out in the claims.

In the accompanying drawings Figure 1 is a view 1n side elevation of a tractor, showin an application of my improvements, an

Figure 2 is a plan view.

In illustrating one form of my invention, I have shown the same in connection with a conventional form of tractor generally indicated by the reference character 1 in which the frame is preferably made of two sections, namely a rear transmission mechanism and axle housing section indicated generally by the reference character 5 and a forward section which constitutes the crank case pan and bearing for the front steering bracket. This section is indicated generally by the reference character 7 The adjacent ends of these sections, namely 5' and 7 are provided with laterally projecting flanges 3 and 4 respectively, by means of which these sections are secured together to form a single longitudinally extending frame as clearly shown in Fig. 1 of the drawings. The forward frame section 7 includes a crank case or a pan 6 which in turn is formed integrally with a forwardly projecting portion as shown at 8 which forms the support for the radiator of the tractor. Formed integrally with and projecting downwardly from this forward portion 8' of the forward frame section 7 is an annular bearing barrel 9 in which is j ournaled or swiveled the front wheel bracket 5 which in turn has journaled therein, the front steering wheel 4. Formed integrally with the front frame section 7' and located on the opposite side thereof are two spaced apart bearing brackets generally indicated by the reference character 7 which in turn have semi-circular sockets for receiving and securing therein, a transverse implement supporting beam or bar 8. This beam 8 is secured in these bearing brackets 7 by means of damp ing jaws 10 and bolts 11. The bearing brackets 7 are reinforced by longitudinally extending ribs 9 which are also formed integrally with the forward frame section 7 The rearward frame section 5' is supported on traction wheels 2 through the medium of the axle sections 3 which extend into the rear frame housing. Formed integrally with the rear frame section 5 is a transmission housing 13 which has its lower wall thereof as shown at 14 slightly elevated above the bottom of the rear axle housing of the rear frame section 5'. Extending longitudinally of and in the center of the rear frame section 5' is a rib 13 which extends from the flange 3 to the rear housing portion. Extending transversely through the longitudinal rib 13 is an aperture 12'. Formed integrally with the transmission housing 13 and also the clutch housing are spaced apart bearing brackets 14 which are located on the opposite sides of the rear frame section 5' and are provided with semi-circular sockets located in transverse alignment with the aperture 12 in the rib 13' for receiving therein a second-transverse implement supporting beam or bar 12. This beam or bar 12 is secured in these brackets by means of clamping jaws 15 and bolts 16.

It will be noted that the transverse bar or beam 8 is located adjacent to and rearwardly of the vertical axis of the swivel bracket 5 and also rearwardly of the axis of the front steering wheel 4 and is secured to the front frame section below the front portion of the crank case or oil pan 6. These transverse bars or supporting implement beams are preferably tubular in form and have their outer ends terminating approximately line with the rear traction wheels 2, but to adapt them to receive certain types of agricultural implements, these beams or bars may be shortened or may be lengthened to a point beyond the line passing longitudinally through the tread of the traction wheels for the purpose of accommodating different types of agricultural attachments. It will be further noted that the transverse beam 12 extends under the lower wall of the transmission and clutch housing and is secured to the rear frame section through the medium of the spaced apart brackets formed integrally with this section.

The lower portion of the crank case or oil pan 6 of the tractor, is provided near its forward end with bearings 7 for a transverse bar or beam 8. It will be observed that this transverse implement supporting beam 8, is located adjacent to and rearwardly of the vertical axis of the swivel bracket 5' and also rearwardly of the axis of the front steering wheel 4. In the present instance the bearings 7 are reinforced by ribs 9 and these ribs and bearings form, in effect, brackets which receive the intermediate portions of the bar or beam 8,the latter being securely fixed to the bearing brackets on the crank case or oil pan by means of clamping jaws 10 secured by bolts 11 passing through said jaws, the bar or beam and the bearing brackets.

The transverse bar or beam 8 is shown in the form of a tube which passes under the crank case or oil pan 6 and projects laterally from the same in both directions.

Another transverse bar or beam 12 (which is also preferably tubular in form) is secured to an intermediate portion of the tractor frame and extends through an aperture 13' in the frame structure, at a point under the transmission and clutch housings 13 of the tractor and projects through an aperture 12 formed in a longitudinally extending housing rib 13'. This beam extends laterally in both directions from the tractor. The transmission and clutch housings 13 are provided with bearing brackets 14 to receive the rear transverse bar or beam 12 and the latter is secured to said bearing brackets by means of jaws 15 secured by bolts 16 which pass through said jaws, the bar or beam 12 and the bearing brackets 14..

In the drawings, I have shown the trans verse bars or beams 8 and 12 as terminating approximately in line with the rear traction wheels 2, but to adapt them to receive certain types of agricultural implements, said bars or beams may be made shorter and for the accommodation of other agricultural implements, said bars or beams may be made of such length as to project outwardly beyond alignment with the traction wheels, or if found expedient in any instance, one of said bars or beams might be made longer than the other.

example, as cultivators, planters, grass mowers, hay rakes, sprayers, scrapers or 1n fact any attachment which it might be desired to applly to a tractor or use in connection therewit 1 Having fully described my invention, what I claim as new and desire to secure by Letters-Patent, is
